Scientists make stretchy electronics using a soup ingredient
For smart clothing or skin-worn devices to improve, first we need electronics that won't snap like a twig when you move. Using a soup thickener, of all things, scientists from Stanford's Bao Lab created a flexible electrode with "uncompromised electrical performance and high stretchability," said lab director Zhenan Bao. The material could one day be used in better brain-monitoring electronics and smart clothing embedded with heart sensors, LEDs and other tech.
NCSU creates stretchable conductors from silver nanowires, lets gadgets go the extra inch
As often as we've seen flexible electronics, there haven't been many examples that could stretch -- a definite problem for wearables as well as any gadget that could afford to take a pull or squeeze. North Carolina State University's Yong Zhu and Feng Xu may have covered this gap through a form of silver nanowire conductor that keeps the energy flowing, even if the wire is stretched as much as 50 percent beyond its original length. By coating the nanowires with a polymer that traps the silver when solid, the researchers create an elastic material that can crumple and let the nanowire take the strain without interruption. Although the stretchy conductor's nature as a research project could put any practical use years into the future, Zhu notes that it can take loads of abuse, making it a perfect fit for rugged mobile devices. It should also allow for robots with a gentler touch and a more natural look... although we'll admit we're skittish about the creepy androids likely to follow.
